To all whom it may concern:

Be it known that I, FREDERICK WILLIAM YICKER-Y, a subject of the King of Great Britain, residing at Glenborn House, 'Ki'ng Edwards Road, Bushey, county of Hertford,

England, have invented certain new and useful Improvements in and Connected with Feeding Mechanism of Printing, Ruling-and Like Machines, of which specification.

' My invention relates to improvements in and connected with feeding mechanism of printing, ruling, and like machines, and espe the following is a cially that class of apparatuswherein suctionis employed to lift a sheet of aper from the be of Well known concave'or conveXformartion'asat Fig. 6,' or the guards positioned so pile and carry it to the feed ro lers.

My invention .will be clearly understood from the following description aided by the accompanyingdrawingsimwhichz Figure 1. is a side. view of-a suction nozzle and adjustable'guard ivoted to a reciprocating axle" operated any part of a printing, ruling or 'like machine,-' the guard eing shown resting.ona:'pileof,p%ger.= .Fig.

2 is a frontelevatlon-of same. 5 3. is a similar view to Fig. 2, but with an a' 'ustable blower attached. 1 Fig.4. is'a'fro'nte evation of 1g. 3. .Fig. 5. is a side elevation showin thesuction nozzle and guard in the raise position and with the top sheet of aper situate at the front of the pile of paper.

, Fig; 6, is a front elevation of a nozzle having nozzles 1', and guard 4, Im'y arrange blowa curved nose. a

My invention conslstsprincipallyofposi-' tiomng the suction nozzle 1 at the required.

distance from the top sheet 2 of paper by 'means of adjustable guards or distancing pieceswhichrest on the pile of paper, so that the suction will draw or attract the to sheet 2 toward the nozzles 1 more efficient y, and thus create a better release from the next sheet. T a

The nozzles 1 'are arranged in Independent bearings such as on arotating axle 3,"a1 1d preferably at opposite corners of the sheet, and used in conjunction with adjustable uards or distancing pieces 4, which a caring on the paper, will only liftthe corners previous to retiring and carrying the top.

sheet with it.

In some cases, in addition to'the suction ing nozzles 5, which act onthe'edg'fl of the emg.

meeting the top edges of the pile of paper to separate/the f sheets'before thGSUCi/IOII takes place, as will be understood Figs. 3 and 4'.

Instead of the guards or distancin pieces. 4

zles, they may be separate, and the position .of such guards fordista'ncing pieces is deter:

mined bythe thickness of paper bein printed being attached-to'or forming part 0 the. noz- I I on ;'the thickerfithe paper, the closert enozzle 3 is to it. y

In some cases, the. mouth of the nozzlemay as to form a corrugation so as tojcorrugate vthe sheet at that p'artyand such nozzle may beof curved formation, and after the sheet has; been held to it'olf-thein by suction, the

movement of the nozzles to carry the sheet upwards-will kink the papenand. in so doing,

positively rlease a second sheet should by any chance one be'attached or held to the top sheet. f f I the drawings, the suction nozzle 1- is pivotally connected to a reciprocating rod 3,

moved by any. part of the machine, and such nozzle lisp'rovided with a tube or nipple 6 to which is attached'a'flcxible tubelconnected with'a pu'm operated from the machine.

1 On theax e 3 toeach nozzle, I secure two lugs 7, 8, which have'action on the suction nozzles .1 to lift and lower them, and one lug 7 isprovided with an adjusting screw 9 to lowerth'elnozzles to theproper distance.

.On the tube or nip le 6 as at Figs. 1' and 2 'I attach a lug 10, til

havin the guard 4, which ispositioned' to he nozzle at the determined. position acis carrying a screw 11 hold t v cordingto the thickness of paper being fed, and in some-cases I also connect to the tube or nipple 6 a blowing nozzle 5, as at Figs; 3, 4 and 5, a flexible tube being connected to the 'pple 6 from a pump operated by the mach ne.

' number of suction nozzles and blowers may ee nployed in one machine, and each beconnected by flexible tubing to the pum "Y- Thej blowing nozzlesmay have indepen exit bearing on the paper to insure the air be determined y a distance guard as on sucsheets, or the distance may tion nozzles.

' when the nozzle is at its lowermost In all cases, the lifting is done by suction.

What I claim and desire to secure by Letters Patent'gis: 4 1., Feed g, mechanism of the class described comprising a'rotary axle, a suction" nozzle mounted, in'pivotal relation thereto,

lugs on said axle for advancing and retracting.

scribed comprising an operating shaft, a suctlOIl' nozzle operativelyyconnected thereto and movable t0ward and from a stack of paper, a posit oning guard mounted in fixed relation to and at a fixed distance to one side 1 of said nozzle and movable therewith, the

scribed comprisin guard being arranged to press upon a pile of paper'when-the nozzle is in its lowermost positlon, a blowing nozzle. arran ed at the opposite side of the suction nozz c with respect to said uard and means for adjusting the guard re atively to the nozzle in a plane parallel to the plane of movement of the latter to vary the distance betweenthe nozzle and the stack of paper. v

3. Fee ding mechanism of the class dea rock shaft, a nozzle piv-- I otally mounted t ereon and rovided-with an air exhausting tube, a guar movable with the nozzle and arranged to cooperate with the top of a stack of paper to position the nozzle a proper distance therefrom, and 'a pair of oppositely arrandged operating lugs mounted on said shaft an arranged to cooperate with, the nozzle to'elevate and de ress the latter, one of the lugs bein provi ed with an ad justing screw where y the position of the the nozzleis in its lowermost position, and a blowin nozzle carried by and mounted in fixed re ation to the suction nozzle, the blowing nozzle having an orifice arran 'ed on the opposite side of the suction nozz e with respect to said guard and adjacent to the edges 0 the sheets composing the 11c.

5. Feeding mechanism 0 the class described comprising an operating shaft, a suction nozzle operatively connected thereto and movable toward and from a stack of paper, a positioning guard mounted in fixed relation to and at one side of the nozzle and adapted to press upon the stack of ,paper when the said nozzle is in its lowermost position; a blowing nozzle also carried by and mounted in fixed relation to the suction noz zle at the opposite side of the latter with res ect to'said guard and having an orifice for lscharging air against the edges of the sheets ofthe stack, and a supplemental blowin nozwardly upon the tops of the sheets in a path transverse to the path of the air from the blowing nozzle first mentioned.

zle stationary with respect to the stac and having an orifice for directing air down- In vtestimony whereof I have hereunto set my hand in presence of two subscribingwitnesses. v v w p FREDERICK WILLIAM VICKERY. Witnesses:
